Grad Students Rush?

[Tess_DreamBig]

Hey all, I'm a senior at Arizona State University and never rushed for a sorority. I was born and raised in Arizona, so I had a lot of friends going to ASU with me and decided against rushing. Now I'm looking into going out of state for grad school next year, either University of Central Arkansas or University of Alabama, and was wondering, especially since these are Southern schools, if I have any shot at all getting a bid for a sorority as a grad student. I will be 22 at the time of fall rush, which is still young, yet considerably older than most of 18 and 19 year olds who will be rushing at that time. I know there are many sororities at both of those schools who claim to accept grad students, but I am sure it's not often.
This brings me to my next question, would it be better to go through informal recruitment at ASU and try to get a bid in a sorority that has a chapter at the school I end up going to so I can attempt to simply transfer over to that chapter when I move?

Thanks for any help or advice you can give!
